Can You Microwave Dunkin Donuts Cups?

Can You Microwave Dunkin Donuts Cups?To begin, let me admit that I’m a coffee enthusiast. In fact, my life revolves around it, and I can’t seem to get enough of it. The nutty, roasted flavor is what I live for; it evokes a sense of elegance and nobility that no other drink can rival.

But sometimes, I’m pressed for time and need a quick caffeine fix. In such moments, Dunkin’ Donuts’ iced latte is my go-to. I especially love it with a shot of espresso to give me extra boost.

However, many people wonder on can you microwave Dunkin Donuts cups?

Dunkin Donuts cups are not microwaveable. The heat melts the adhesive glue that binds the paper layers together, leaching into your coffee and making it unsafe to consume. Furthermore, the plastic lining inside the cup is distorted, compromising the packaging’s integrity.

Are Dunkin Donuts Cups Microwave Safe?

Can You Microwave Dunkin Donuts Cups?No, when you microwave Dunkin Donuts cups, the adhesive glue that binds the paper layers together melts and leaches into your coffee.

Let me put this in context for you.

Over the years, I have witnessed a steady improvement in Dunkin’ Donut’s packaging quality. In particular, the double-walled paper cups are a significant leap forward from the old days of thin, flimsy single-walled paper cups. These new insulated mugs are sturdy enough to withstand the rigors of a long commute and keep my coffee hot for hours.

However, one major flaw with these otherwise terrific cups is that they do not hold up well when microwaved. You see, the primary material used in constructing these cups is paper and adhesive glue. The glue seals the paper layers, fortifying the cup against leaks and spills.

Unfortunately, when exposed to high heat, the glue becomes brittle and loses its ability to bind properly. And before you know it, your cup crumbles, spilling coffee all over the inside of your microwave, potentially ruining it. Worse, the melted adhesive leaches into your coffee, exposing you to unsafe levels of toxins.

My unsolicited advice, steer clear of microwaving Dunkin Donuts Cups.

 

Can You Microwave Dunkin Donuts Styrofoam Cups?

Absolutely not! The Dunkin Donuts Styrofoam cup will melt, leaching toxic chemicals into your coffee. 

Perhaps a recap on Styrofoam will help you understand why this is such a big concern.

A quick Google search reveals that Styrofoam is a registered trademark for polystyrene foam products developed by the Du Pont Company. And because of its exceptional insulating properties and lightweight, it gained popularity in the building industry. Today, it’s primarily utilized in the food service industry for items like cups, plates, take-out containers, and trays.

There is, however, a problem: Styrofoam is a petroleum-based product that, when heated, emits styrene and benzene. According to the World Health Organization, these chemicals are carcinogenic and have been linked to several major health problems.

So, no, I don’t recommend microwaving your Dunkin’ Donuts Styrofoam at all. The cup will melt, leaching styrene and benzene into your coffee. If you’re looking for an easy alternative, try ceramic cups, which are deemed microwave safe.

 

How To Determine Whether a Cup Is Microwave-Safe

My grandpa once said prevention is better than cure, and I can’t agree more. That being said, there are a few things you can do to establish whether or not your cup is microwave-safe.

 

1. Look for the “Microwave-safe Symbol”

The first and most critical step in microwaving an item is to ensure that it is labeled with the “microwave safe” mark. As a result, every manufacturer must include this emblem on their products to signify microwave compatibility.

 

Usually, it takes various shapes, such as three squiggly lines on top of one another or three wavy lines inside a microwave icon. Additionally, some manufacturers include the words ‘microwave safe’ or ‘safe for microwave use’ in the text on the container base. However, if you have doubts about whether your cup is microwave-safe, don’t risk it.

 

2. Check out the Manufacturer’s Website

If your cup lacks microwave-safe symbols, it’s time to check the company’s website. Most manufacturers will indicate the material composition of their cups, allowing you to evaluate whether or not they are microwave-safe quickly.

 

Additionally, check the care instructions to see if there is a mention that your item is microwavable. For instance, Dunkin Donuts states that their cups are dishwasher safe but not microwaveable. If you still can’t find answers to your questions, contact the company directly. Chances are, they will be happy to help.

 

3. Examine the Material

Not all materials are microwave-safe. For example, paper cups will burn when exposed to heat. On the other hand, Styrofoam cups should be avoided due to the potential chemical leaching into your food.

 

Furthermore, plastic containers with the recycle number 6 contain bisphenol A (BPA), which has been linked to severe health issues. Similarly, aluminum or metal cans will spark and explode, ruining your microwave.

 

Instead, I recommend using ceramic, porcelain, or glass cups. These materials can withstand high microwave temperatures without leaking harmful chemicals into your food or drink.

 

4. Perform a Test Run

I know it sounds ludicrous, but sometimes desperate times call for desperate measures. If you’re anxious about risking your favorite coffee mug, perform a test run before popping it into the microwave.

 

However, I must warn you this is a dangerous path to tread. Microwaving the cup could result in burns, a fire, or even an explosion. In my opinion, attempting a trial run is just not worth the risk.

 

Nevertheless, for the daring, here’s how to conduct a test run. Fill the cup with cold water and microwave for 30 seconds. If the cup remains cool to the touch and intact, you’re good to go. But, if it is hot to the touch or cracks, discontinue using it in the microwave.

 

How To Safely Reheat Dunkin’ Donuts Coffee in The Microwave

Can You Microwave Dunkin Donuts Cups?Although Dunkin’ Donuts cups are not microwave-safe, it doesn’t mean you can’t reheat your favorite coffee in the microwave. Here are a few steps to take to ensure your coffee stays hot and doesn’t turn into a gooey slop.

 

  1. Transfer your cold Dunkin Donuts Coffee into a microwavable mug or container. I recommend using a ceramic, glass, or other microwave-safe containers.

 

  1. Microwave in 30-second bursts or until the desired temperature is attained. Don’t forget to stir your coffee at intervals to ensure even heat distribution.

 

  1. Once piping hot or to your liking, carefully remove your beverage from the microwave. Be sure to use an oven mitt or towel to protect yourself against spills.

 

  1. If desired, transfer your coffee back into the original cup for optimal insulation. I prefer to top it with cream and sugar before serving.

 

Should You Reheat Your Dunkin’ Coffee?

Can You Microwave Dunkin Donuts Cups?Reheating your Dunkin’ Donuts coffee is not recommended as it restructures the coffee’s chemical structure, altering its flavor profile.

I’ll admit, nothing beats a piping hot cup of joe on a cold day. But sometimes, busy schedules disrupt our regimen, leaving us no time for that early morning caffeine fix. To salvage the situation, we often find ourselves on autopilot, sticking the travel mug in the microwave to heat it up.

However, this can have a detrimental effect on the flavor of your drink. Any true java-lover will tell you one thing; coffee is a one-time deal. If it gets cold before you drink it, your only option is to make some more.

Why? Coffee chemical compounds are sensitive and volatile when subjected to high temperatures for extended periods. When reheated, these compounds break down, resulting in the loss of aromatics and flavors, rendering the coffee bitter or flat.

So, while it’s okay to reheat your coffee once or twice, it’s far preferable to brew a fresh cup.

 

How Long Does a Dunkin’ Donuts Coffee Last in The Fridge?

Dunkin’ Donuts’ coffee stored in a sealed container will stay fresh in the fridge for 3-4 days.

However, expect a deterioration of quality after this period. That said, coffee is best served shortly after brewing to maintain optimal flavor. The longer you wait, the more bitter and less flavourful it becomes.

Additionally, unsweetened coffee with no added creamers can last up to 4 hours at room temperature. Contrarily, brewed coffee with creamers or additives only lasts for a few hours before spoiling.

Remember to smell your coffee before drinking it. It should have a roasted, almost nutty aroma. If it smells like anything else, don’t drink it.

 

Bottom Line

Dunkin Donuts cups are not microwaveable, and heating them melts the adhesive glue that binds the paper layers together. Furthermore, the adhesive leaches into your beverage, adding harmful chemicals and causing stains on your microwave. If you want to reheat your favorite coffee in the microwave, use a microwave-safe container instead.
